Email headers not showing on initial load in 1.7-rc4

[ehymel]

I recently updated from version 1.7-beta2 to 1.7-rc4. The problem below has now appeared:

When I first load ANY new unread message, all images in the message are blocked, as expected. However all email headers (From, To, ReplyTo, Date) are also missing (see screenshot). If I click off of the message then return to the new message, now all headers are correctly displayed. If I have previoulsy "allowed all from <email address>" then I see all message images (as expected) or I have the additional button of "Always allow from <email address>" (also as expected).

So, it's just the initial load of any new unread message. I'm not sure which version this problem appeared between beta2 and rc4.

is there anything in the roundcube error log? also do you have any of the imap or message caching options enabled? if so does resetting the cache make any difference?

Thanks for the reply.

No error messages in the roundcube errors.log file, and I am not using any imap or message caching:

Code Select Expand

// config/default.inc.php
$config['imap_cache'] = null;
$config['messages_cache'] = false;

Just in case, I rebooted the entire server and the issue persists.

I still don't have an answer, but it must be some odd caching issue as you suggested @JohnDoe. When I revert back to version 1.7-beta2 and even version 1.6.10 I now get the same behavior. I'll keep investigating and report back here if I find a solution. If anyone has ideas to try, I'm all ears. fwiw, I'm running a fedora 43 server with caddy v. 2.10.2.
